CROSS REFERENCE TO RELATED PATENT APPLICATIONS

The present patent application claims the right of priority under 35 U.S.C. §119 (a)-(d) and 35 U.S.C. §365 of International Application No. PCT/EP2010/58259, filed Jun. 11, 2010, which was published in German as International Patent Publication No. WO 2010/142795 A1 on Dec. 16, 2010, which is entitled to the right of priority of European Patent Application No. EP 09162601 filed on Jun. 12, 2009.

The invention relates to carrier materials containing nitrogen, especially organically bonded nitrogen, to the preparation thereof and to the use thereof for stabilizing iodine-containing compounds, and to binder formulations comprising them and to the use thereof for the protection of industrial materials.

Iodine-containing biocides are used for providing industrial materials, coating materials being an example, with protection from infestation, decomposition, destruction and visual alteration by fungi, bacteria and algae, preferentially by fungi. Furthermore, iodine-containing biocides, both alone and in combination with biocides from other classes of active ingredient, are used as components of biocidally active materials protection compositions such as wood preservatives. Besides iodoalkynyl compounds, the active ingredients used here include compounds in which one or more atoms of iodine are attached to double-bond systems, but also to singly bonded carbon atoms.

A behaviour common to many iodine-containing biocides is that on exposure to light even in bulk or as a component of an industrial material (coating material, for example) they lead to yellowing with breakdown of the active compound. This feature hinders or prevents the use of iodine-containing biocides in materials having such sensitivity, such as in light-coloured or white coating materials, for example. For the IPBC, these instability qualities are described in WO00/16628 for example.

Many iodine-containing biocides, particularly iodoalkynyl compounds, are destroyed with particular rapidity by metal compounds. This fact prevents iodoalkynyl compounds, for example, from being used in solvent-based coating materials, such as paints, varnishes and stains, for example, or in biocidal preservatives, such as wood preservative primers, wood preservative impregnation systems and wood preservative stains, for example, since these alkyd-based coating and preservation systems are regularly equipped with metal compounds. In such systems, transition metal compounds, examples being cobalt, lead, manganese and vanadium octoates, function as dryers (siccatives) for the alkyd resin-containing binder system. Moreover, transition metal compounds are also used as pigments, and in some cases have destructive properties comparable with the siccatives.

In the solvent-based systems referred to above, there are, in addition to the dryers, a series of further ingredients which, to different degrees, lead to breakdown of iodine-containing biocides. Whereas the destabilizing effect is still relatively weak with the solvents that are customarily used, the other customary components of a paint formulation, such as process additives, plasticizers, colour pigments, anti-settling agents, thixotropic agents, corrosion inhibitors, anti-skinning agents and binders, for example, exhibit more or less strongly pronounced destabilizing effects.

As well as in the solvent-based systems described above, problems also attend the use of iodine-containing biocides in certain water-based industrial materials (e.g. coating materials and preservatives such as wood preservative stains and primers). Where the film formation and film hardening of a water-based coating material is based, for example, on the oxidative crosslinking of water-soluble or emulsified alkyd resins, transition metal compounds are employed as siccatives in these systems as well, and their use is accompanied by destruction of the iodine-containing biocides present.

There are already methods known for preventing the degradation of halopropargyl compounds in transition-metal-containing, solvent-based alkyd-resin paints. WO 98/22543, for example, describes the addition of chelating reagents.

Also known are transition-metal-containing, solvent-based alkyd-resin paints where halopropargyl compounds are stabilized by means of organic epoxides (cf. WO 00/16628).

Moreover, there are already descriptions of methods of suppressing the light-induced degradation of active antifungal compounds, such as iodopropargyl butylcarbamate, by addition of tetraalkylpiperidine compounds and/or UV absorbers (cf. EP-A 0083308).

According to WO 2007/028527, iodine-containing biocides are stabilized with 2-(2-hydroxyphenyl)benzotriazoles.

Addition of epoxy compounds is said to reduce the discoloration of iodoalkyne compounds, such as IPBC (cf. U.S. Pat. No. 4,276,211 and U.S. Pat. No. 4,297,258).

Furthermore, there are descriptions of synergistic mixtures of epoxides with UV absorbers (cf. WO 99/29176) and with benzylidene camphor derivatives (cf. U.S. Pat. No. 6,472,424), which likewise exhibit reduced yellowing.

WO 2007/101549, moreover, describes the stabilization of iodine-containing biocides by means of azole compounds.

The stabilizing action of the aforementioned stabilizers, however, is not always sufficient, and carries performance disadvantages. Thus, in particular, the drying times of the paints are markedly prolonged, and in many cases this is unacceptable to the user. Moreover, the inhibition of discoloration is not always sufficient.

Surprisingly, it has now been found that the use of nitrogen-containing inorganic carrier materials makes it possible to provide iodine-containing biocides, particularly in solvent-based and water-based systems, with protection against both chemical and light-induced degradation, and hence to prevent the above-described disadvantages of unstabilized iodine-containing compounds, such as alterations to colour and loss of active compound/activity. It has been found, moreover, that using nitrogen-containing carrier materials to stabilize iodine-containing biocides in the aforementioned systems engenders no performance disadvantages, such as the prolongation of the drying time of a coating system, for example.

Aziridine compounds are employed, for example, in US2004/0077783 A1 as part of polymerization initiators which as further ingredients comprise organoborane compounds, carrier materials and optionally fillers. The latter are present as a concomitant of the preparation process, but as mixtures with the other components, and not as carrier materials surface-modified with aziridine.

Through the use of inorganic carrier materials containing nitrogen, the specific properties of liquid, iodine-containing formulations, e.g. solutions and dispersions, such as, for example, low concentration and hence unnecessary transport of solvent, are improved still further. As compared with iodine-containing solutions, this form possesses, in particular, stability advantages, particularly in storage, preferably at elevated temperatures.

In one aspect, therefore, the invention relates to nitrogen-containing inorganic carrier materials. Nitrogen-containing inorganic carrier materials in the context of the invention are inorganic carrier materials comprising at least one absorptively or covalently bonded, nitrogen-containing compound.

For clarification it is noted that the term “nitrogen-containing inorganic carrier materials” also encompasses those inorganic carrier materials which comprise in each case absorptively and covalently bonded nitrogen-containing compounds, and also those inorganic carrier materials comprising different nitrogen-containing compounds, of which at least one is covalently bonded and at least one is adsorptively bonded.

In one preferred embodiment, the nitrogen-containing inorganic carrier materials comprise the nitrogen in organically bonded form, where, for the purposes of the invention, organically bonded nitrogen means nitrogen which has at least one bond to a carbon atom, with the exception of cyanide and isocyanate ions and of prussic acid and isocyanic acid.

For clarification and in order to simplify the nomenclature, it is noted that the term “nitrogen-containing inorganic carrier materials” also encompasses those materials in which the inorganic carrier materials comprise covalently bonded nitrogen-containing compounds in which the nitrogen is organically bonded.

The nitrogen-containing inorganic carrier materials of the invention are preferably solid at room temperature.

The nitrogen-containing inorganic carrier materials of the invention are prepared preferably by reaction of inorganic carrier materials with at least one nitrogen-containing compound, the nitrogen-containing compounds preferably being organic compounds.

In one preferred embodiment, nitrogen-containing inorganic carrier materials of the invention have a nitrogen content of 0.05% to 10% by weight, preferably of 0.1% to 10% by weight. Unless indicated otherwise, nitrogen contents are determined quantitatively by elemental analysis using a combustion method.

Since, in the reaction of nitrogen-containing compounds with the inorganic carrier materials, especially in those cases in which covalent bonds are formed as well, the reaction mechanisms are frequently opaque, multilayered and not amenable to full structural elucidation, the invention also encompasses nitrogen-containing inorganic carrier materials comprising compounds obtainable through reaction of inorganic carrier materials with nitrogen-containing compounds, where the preference ranges specified for nitrogen-containing inorganic carrier materials in general apply in the same way

Suitable inorganic carrier materials are for example and preferably silicas such as, for example, precipitated silicas, such as silica gels, mesoporous silicates, xerogels, aerogels, fumed silicas, silicas modified with organic, inorganic or organometallic radicals, examples being dichlorodialkylsilane-modified silicas, kieselguhr, porosils, e.g. zeosils, clathrasils or dealuminated zeolites, aluminosilicates, zeolites, natural or synthetic tectosilicates, natural silicates such as, e.g., vermiculite, mica or pyrogenic metal oxides, for example TiO₂, including pyrogenic mixed metal oxides.

Preference is given to fumed silicas, more particularly hydrophilic or hydrophobic ones, as for example those in commerce under the name Aerosil® from Evonik-Degussa, the product Aerosil® 200 being particularly preferred.

It is also preferred for the inorganic carrier material, in the event that the heterocyclic 3-membered-ring compound is an aziridine, does not comprise any organoborane.

The DBP absorbency of the carrier materials of the invention is preferably 0.1 to 800 g/100 g, more preferably 1 to 500 g/100 g of carrier material.

The nitrogen-containing inorganic carrier materials of the invention preferably possess a specific surface area [m²/g], determined in a method based on that of Brunauer, Emmett and Teller (BET surface area; J. Am. Chem. Soc. 60, 309 (1938)), in accordance with ISO 5794/1 (Annex D), of 1 to 1200 m²/g, more preferably of 50 to 900 m²/g.

Preference is given to employing a composition comprising

-   a) at least one nitrogen-containing inorganic carrier material of     the invention -   and -   b) at least one iodine-containing biocide.

The composition is likewise provided by the present invention.

With regard to the preferred iodine-containing compounds, more particularly biocides, and the preferred carrier materials of the invention, the forms of preference specified above apply to the preferred compositions of the invention as well.

Particularly preferred compositions comprise

-   a) at least one nitrogen-containing inorganic carrier material, and -   b) IPBC.

The compositions of the invention contain generally 0.01-70%, preferably 0.05%-60%, more preferably 0.1%-50% by weight of at least one iodine-containing biocide and at least one nitrogen-containing inorganic carrier material of the invention, and so the amount of all of the nitrogen-containing inorganic carrier materials present in the composition of the invention is 0.001%-80%, preferably 0.005%-60%, more preferably 0.01-50% by weight.

The composition of the invention preferably comprises the iodine-containing biocide and nitrogen-containing inorganic carrier materials in total from 40% to 99% by weight.

The composition of the invention may be present in a variety of forms—for example, as a solvent-based dispersion, water-based dispersion, solids mixture, etc.

With particular preference, the composition of the invention takes the form of a solid mixture, such as, for example, a powder or granules, more particularly having an average particle size of 50 to 2000 μm, or a compacted formulation, such as, for example, compacted powder such as, for example, pellets, tablets, etc.

Likewise with particular preference, the composition of the invention takes the form of a solvent-based dispersion, where, in order to adjust the rheological properties of the dispersion, for example, alkyd resins, modified alkyd resins, thixotropic resins, etc., and also further additives such as anti-skinning agents (antioxidants), pigments, crystallization stabilizers, etc., may be added.

The invention further provides a process for preparing the composition of the invention.

The composition of the invention may be prepared, for example, by mixing the individual components, i.e. the nitrogen-containing inorganic carrier material and the iodine-containing compound, optionally with extenders and optionally using further adjuvants such as, for example, flow improvers, additives for increasing the electrical conductivity, additives for adjusting the dusting characteristics, etc. For preparing the composition of the invention in the form of solids Mixtures, use is made here, optionally after pretreatment of the components that are to be mixed, using, for example, sieve mills such as the Bauermeister mill, of suitable solids mixers such as, for example, Lödige mixers, paddle mixers, tumble mixers, drum mixers with disruptors, etc. Additionally, the conversion of resultant solids mixtures into further embodiments, such as granules, compacted forms such as pillows, tablets, etc., for example is possible with use of fluid-bed granulation, use of mechanical compacting systems, optionally with addition of further additives such as binders, for example.

Another embodiment of the composition of the invention is a solvent-based dispersion comprising an iodine-containing compound, in particular IPBC, and at least one nitrogen-containing inorganic carrier material of the invention, in particular one in which the heterocyclic 3-ring compound is at least one aziridine compound. In this case, the iodine-containing compound, in particular IPBC, and the nitrogen-containing inorganic carrier material of the invention are ground and dispersed (e.g. bead mill), preferably with strong shearing in an inert organic solvents as the continuous phase (e.g. isoparaffins such as Isopar® L (isoparaffin from Exxon) or “white spirits” such as, for example, Sheilsol® D60), optionally with addition of process auxiliaries and stabilizers such as, for example, rheological additives (thixotroping resins such as, for example, WorleeThix S6358, a thixotroped alkyd resin from Worlee) and optionally anti-skinning agents such as, for example, Antiskin® 444 (from Borchers).

The activity and the spectrum of action of the compositions of the invention and/or of the iodine-containing compound employed may be increased by adding, optionally, further antimicrobial compounds, fungicides, bactericides, herbicides, insecticides or other active compounds, so as to widen the spectrum of activity or to obtain particular effects, or by using such compounds at the same time.

The invention further provides a binder formulation comprising

-   -   at least one binder,     -   at least one iodine-containing compound, more particularly         biocide, and     -   at least one nitrogen-containing inorganic carrier material of         the invention.

The binder formulation preferably comprises the ‘iodine-containing compound, more particularly biocide’, and ‘nitrogen-containing inorganic carrier materials of the invention’ components in the form of the composition of the invention. Preferred binders contemplated include oxidatively drying binders, preferably alkyd-resin-based binders, or binders which form films by means of coalescents, especially lattices.

The alkyd-resin-based binders contemplated are preferably alkyd resins and modified alkyd resins.

The alkyd resins are, in general, polycondensation resins formed from polyols and polybasic carboxylic acids and/or their anhydrides, and fats, oils or free natural and/or synthetic fatty acids. The alkyd resins may optionally also be modified chemically with hydrophilic groups, especially water-soluble groups, in order that they can be used, for example, as an emulsifiable or as a water-soluble alkyd resin.

The stated polyols are preferably glycerol, pentaerythritol, trimethylolethane, trimethylolpropane and various dials such as ethane-/propanediol, diethylene glycol and neopentyl glycol.

The stated polybasic carboxylic acids and/or their anhydrides are preferably phthalic acid, phthalic anhydride, maleic anhydride, isophthalic acid, terephthalic acid, trimellitic anhydride, adipic acid, azelaic acid or sebacic acid.

The stated oils or fatty acids are generally linseed oil, oiticica oil, tung oil, soya oil, sunflower oil, safflower oil, ricinene oil, tall oil, castor oil, coconut oil, peanut oil, their fatty acids, and also synthetic saturated, unsaturated or polyunsaturated monocarboxylic acids or mixtures of these components.

The alkyd resins can optionally also be modified with, for example, natural resins, phenolic resins, acrylic resins, styrene, epoxy resins, silicone resins, isocyanates, polyamides or aluminium alkoxides.

The alkyd resins generally have a molar mass of 500 to 100 000 g/mol, preferably of 1000 to 50 000 g/mol, more particularly of 1500 to 20 000 g/mol, (determined by laser light scattering; see, for example, “Static Light Scattering of Polystyrene Reference Materials: Round Robin Test”, U. Just, B. Werthmann International Journal of Polymer Analysis and Characterization, 1999 Vol. 5, pages 195-207).

The binder formulations of the invention comprise preferably 1% to 80%, more preferably 2% to 70% and with particular preference 3% to 60% by weight of alkyd resin.

The binder formulation of the invention preferably comprises an alkyd-resin-based binder and a transition metal dryer for oxidative drying. Transition metal dryers for the purposes of this specification are more particularly transition metal compounds which accelerate the drying and curing of the alkyd-resin-based binder.

Preference is given to the salts of transition metals of groups Vb, VIb, VIIb, VIII and Ib of the chemical periodic system. These are more particularly the salts of cobalt, manganese, vanadium, nickel, copper and iron, more preferably cobalt, manganese, iron and vanadium. They need not necessarily be used alone, but instead can also be employed in combination with non-transition metal salts, such as lead, calcium or zirconium, for example.

The preferred transition metal salts are soluble in organic solvents, for example, white spirit at 20° C. in an amount of more than 10 g/l. The salts in question are preferably the salts of carboxylic acids, which have high compatibility with the alkyd resin binders and at the same time ensure sufficient solubility of the metal salt. Preference is given to using transition metal salts of fatty acids, such as oleates or linoleates, resin acids such as resinates, or salts of 2-ethylhexanoic acid (octoates). Preferred transition metal dryers are cobalt octoate and cobalt naphthenate, e.g. Octasoligen®-Cobalt 12 from Borchers.

The binder formulations of the invention preferably comprise the transition metal dryers in an amount of 0.001% to 1%, preferably 0.005% to 0.5% and very preferably 0.01% to 0.1% by weight, based in each case on binder.

In one preferred embodiment the binder formulations comprise at least one polar organic solvent, preferably a polar aprotic solvent. Examples of suitable such polar protic solvents are those such as dipropylene glycol monomethyl ether (e.g. Dowanol DPM from Dow Chemical) and also, preferably, in combination thereto, polar aprotic solvents, such as dimethylformamide and dimethyl sulphoxide, and also, for example, etherified glycols, oligoglycols and polyglycols, etherified polyols and esterified polyols, esters of monobasic and polybasic carboxylic acids, e.g. diisobutyl adipate, diisobutyl maleate, (e.g. Rhodiasolv DIB).

Particular preference is given to the binder formulation comprising

1% to 80%, preferably 2% to 70%, more preferably 3% to 60% by weight of alkyd resin binder(s) 0% to 50%, preferably 0% to 45%, more preferably 0% to 40% by weight of colour pigments 0.01% to 5%, preferably 0.05% to 3%, more preferably 0.1% to 2% by weight of iodine-containing compound, in particular biocide, 0.001% to 7%, preferably 0.005% to 5%, more preferably 0.01 to 4% by weight of nitrogen-containing inorganic carrier materials, 2% to 97% by weight of solvent(s), more particularly non-polar or polar solvents, including preferably up to 10%, more particularly 0.01% to 7.5%, by weight, based on the binder preparation, of polar aprotic solvents, and 0.001% to 3% by weight of a transition metal dryer.

Particularly preferred binder formulations of the invention are those comprising at least one alkyd resin, at least one transition metal dryer, IPBC, at least one solvent and at least one nitrogen-containing inorganic carrier material of the invention.

The binder formulation may further comprise fillers, anti-skinning agents, rheological additives such as, for example, anti-settling agents and thixotropic agents, further biocides such as fungicides, bactericides, anti-fouling agents and algicides, solvents, process additives, plasticizers, UV stabilizers and heat stabilizers, and also corrosion inhibitors, in customary amounts.

It is additionally possible to add further stabilizers to the binder formulations, examples being the chelating reagents specified in WO 98/22543, or heterocyclic 3-membered-ring compounds, in particular those with a different heteroatom from nitrogen, such as for example the organic epoxides specified in WO 00/16628. In many cases synergistic effects are observed here.

In the context of the inventive use it is also possible, furthermore, to add one or more stabilizers from the group consisting of antioxidants, free-radical scavengers, UV stabilizers, chelators and UV absorbers, which in some cases exhibit synergistic effects.

Further UV stabilizers that may be mentioned include, by way of example, the following:

Iodine-containing compounds, more particularly biocides, are degraded in particular in the presence of the dryers described in more detail above. Although the strongest effects are observed in the presence of these dryers, a series of further paint components also have a destabilizing effect on iodine-containing compounds, more particularly biocides. These include organic and inorganic pigments, fillers, anti-skinning agents, rheological additives such as, for example, anti-settling agents and thixotropic agents, further compounds, particularly biocides such as fungicides, bactericides, anti-fouling agents and algicides, solvents, process additives, plasticizers, UV stabilizers and heat stabilizers, corrosion inhibitors, etc. The nitrogen-containing inorganic carrier materials of the invention also display a strongly stabilizing effect here.

The compositions of the invention, used in oxidatively drying binder preparations, and the binder preparations of the invention themselves exhibit a significant reduction in drying time as compared with unstabilized iodine-containing systems, particularly systems containing IPBC or no increase in drying time as compared with the systems not equipped with IPBC (known as blank formulations).

Without the applicant wishing to state this as a scientific certainty, it is presumably the case that the mechanism which takes place is different from the removal of metal ions, as described, for example, with polymers of aziridines for the removal of heavy metal ions from wastewaters in DE-A1-19627909. Removal of heavy metal ions would diminish the activity of the siccatives employed for this purpose, and would therefore prolong the drying time accordingly.

The binder formulations of the invention are used preferably as coating materials, more particularly as paints, varnishes, primers, impregnating systems and stains. Accordingly, the invention also provides for the use of the binder formulations of the invention as coating materials.

The invention further provides for the use of the composition of the invention for protecting industrial materials against destruction or infestation by microorganisms.

The compositions of the invention are suitable for protecting industrial materials. Industrial materials in the present context are non-living materials which have been prepared for use in industry. The industrial materials are, for example, adhesives, sizes, paper and cardboard, textiles, leather, wood, wood-based materials, coating materials and plastics articles, cooling lubricants and other materials which may be infested or decomposed by microorganisms.

Examples of microorganisms which may bring about degradation or alteration of the industrial materials include bacteria, fungi, yeasts, algae and slime organisms. The active compounds of the invention act preferably against fungi, more particularly moulds, wood-discolouring and wood-destroying fungi (Basidiomycetes) and also against slime organisms and bacteria.

Microorganisms of the following genera may be mentioned by way of example:

Alternaria, such as Alternaria tenuis, Aspergillus, such as Aspergillus niger, Chaetomium, such as Chaetomium globosum, Coniophora, such as Coniophora puetana, Lentinus, such as Lentinus tigrinus, Penicillium, such as Penicillium glaucum, Polyporus, such as Polyporus versicolor, Aureobasidium, such as Aureobasidium pullulans, Sclerophoma, such as Sclerophoma pityophila, Trichoderma, such as Trichoderma viride, Escherichia, such as Escherichia coli, Pseudomonas, such as Pseudomonas aeruginosa, Staphylococcus, such as Staphylococcus aureus.

The invention further provides industrial materials comprising at least one iodine-containing compound, in particular biocide, and at least one inorganic carrier material of the invention.

EXAMPLES

In the examples below, stability tests accelerated by storage at elevated temperature are carried out. The IPBC was assayed in all cases by HPLC.

Examples 1-5

Examples 1-5 describe the preparation of inventive nitrogen-containing inorganic carrier materials from inorganic carrier materials and nitrogen-containing compounds, and inventive compositions comprising IPBC and aforesaid carrier materials. Nitrogen contents were determined by means of combustion analysis on the Leco TruSpec CHN instrument.

Example 1 Reaction Product of Aerosil with Aziridine I

The oil phase, consisting of 9.0 g of Crosslinker CX-100 from DSM (trimethylolpropane tris[3-(2-methyl-1-aziridinyl)propionate]) and 2.5 g of Rhodiasolv® DIB from Rhodia (mixture consisting of diisobutyl adipate, diisobutyl glutarate, diisobutyl succinate) was emulsified with a solution of the emulsifier of 0.575 g Tanemul® KS from Tanatex (castor oil ethoxylate with 30 eq. EO) in 25 g of water under the action of an Ultraturrax (24 000 r*min⁻¹) for 10 minutes. The colourless emulsion obtained was metered into a dispersion of 27.0 g of Aerosil® 200 from Evonik (fumed silica having a BET surface area of 200 m²/g and a DBP absorbency of 300 g/100 g) in 300 g of water with paddle stirring, followed by stirring for 24 hours.

The Aerosil loaded with the aziridine and Rhodiasolv DIB was isolated from the resultant dispersion by spray drying (Büchi B-290 spray dryer, pump output 45%, N₂ flow rate 35 l*min⁻¹, inlet 160° C., outlet 73° C.). This gave 33 g of a very fine, colourless solid (84% of theory).

In the elemental analysis, a nitrogen content of 2.0% was found.

For determining unreacted aziridine, 3.358 g of the above product was stirred at room temperature for 2 hours with 14.32 g of tetrahydrofuran, centrifuged at 13 000 rpm for 5 minutes and subjected to semiquantitative determination in the supernatant by means of LC-MS. The solution contained 1-10 ppm of the aziridine. Converted to the solid, this corresponds to a residual concentration of unreacted aziridine of between 4 and 43 ppm.

Example 1b

3.0 g of the product from Example 1 were admixed with 15 g of THF and stirred at room temperature for 2 days. The solid was subsequently isolated by filtration, washed twice with hexane and dried under reduced pressure. This gave 2.5 g of a white powder.

Example 2 Reaction Product of Aerosil with Aziridine II

The oil phase, consisting of 18.0 g of Crosslinker CX-100 from DSM (trimethylolpropane tris[3-(2-methyl-1-aziridinyl)propionate]) and 5.0 g of Rhodiasolv® DIB from Rhodia (mixture consisting of diisobutyl adipate, diisobutyl glutarate, diisobutyl succinate) was emulsified with a solution of the emulsifier of 1.15 g Tanemul® KS from Tanatex (castor oil ethoxylate with 30 eq. EO) in 50 g of water under the action of an Ultraturrax (24 000 r*min⁻¹) for 10 minutes. The colourless emulsion obtained was metered into a dispersion of 54.0 g of Aerosil® 200 from Evonik (fumed silica) in 600 g of a solution of 24 g of the dispersing assistant Mowiol® 3-85 (polyvinyl alcohol from Kuraray) in 576 g of water, with paddle stirring, followed by addition of 600 g of water and then by stirring for 24 hours.

The Aerosil loaded with the aziridine and Rhodiasolv® DM was isolated from the resultant dispersion by filtration. Drying gave 75.4 g of a very fine, colourless solid (98% of theory).

Example 3 Inventive Solid IPBC Composition I

IPBC (90.0 g) is homogenized with 128.4 g of the nitrogen-containing inorganic carrier material from Example 2 (containing 23.2% of aziridine, so making the weight ratio of IPBC to aziridine 4:1) with addition of ceramic beads (φ 40 mm) in a drum mixer. This gives a fine, colourless and homogeneous powder (IPBC content 41%).

Example 4 Inventive Solid IPBC Composition H

IPBC (90.0 g) is homogenized with 96.9 g of the aziridine formulation from Example 2 (containing 23.2% of aziridine, so making the weight ratio of IPBC to aziridine 3:1) with addition of ceramic beads (φ 40 mm) in a drum mixer. This gives a fine, colourless and homogeneous powder (IPBC content 48%).

Example 5 Inventive Solid IPBC Composition III

IPBC (90.0 g) is homogenized with 128.4 g of the aziridine formulation from Example 1 (containing 23.03% of aziridine, so making the weight ratio of IPBC to aziridine 4:1) with addition of ceramic beads (φ 40 mm) in a drum mixer. This gives a fine, colourless and homogeneous powder (IPBC content 41%).

Example 6 Inventive IPBC Composition IV as Solvent-Based Dispersion

Metered into 75.0 g of the rheological additive Worleethix® S6358 (a thixotroped alkyd resin from Worlee) with dissolver stirring (3700 r min⁻¹) are 8.0 g of the anti-skinning agent Antiskin® 444 (Borchers), 80 g of IPBC, 113.1 g of the inventive carrier material from Example 2 (containing 23.2% aziridine) and 225.9 g of Isopar® L (Isoparaffin from Exxon). After the end of the addition, stirring on the dissolver is continued for 40 minutes more, and the resulting preliminary dispersion is ground finely using a bead mill.

Example 7 Use of Inventive Nitrogen-Containing Inorganic Carrier Materials in Binder Formulations

The IPBC compositions from Example 3 and 4, respectively are incorporated in a typical, alkyd-based coating system (alkyd stain A) in the presence of a transition metal dryer (Co) and a metal oxide pigment (iron oxide). For the equipping of the coating system, the above-mentioned compositions from Example 3 and 4, respectively, and, an IPBC concentrate containing IPBC and an aziridine in a ratio of 2:1 (see Table 1) without inorganic carrier material are used in each case.

TABLE 1 IPBC/aziridine concentrate (reference II) IPBC 30% by weight Crosslinker CX-100** 15% by weight Rhodiasolv DIB* 55% by weight *Mixture of diisobutyl adipate, diisobutyl glutarate, diisobutyl succinate, Rhodia. **Trimethylolpropane-tris[3-(2-methy1-1-aziridinyl)propionate]

The formula of the alkyd stain A used is shown in Table 2.

To determine the stabilization, an accelerated ageing test is carried out. For this purpose, the equipped paint system is introduced into tightly sealing 200 ml glass bottles, with only a minimum, residual amount of air remaining in the container, and stored at 40° C. The results can be seen from Table 3.

From Table 3 it is clear that the nitrogen-containing inorganic carrier materials of the invention, in terms of the stabilization of IPBC (see stains A-I and A-II), have a significantly higher stability than the unstabilized sample A-III. There is also a significant improvement relative to the IPBC sample stabilized only with aziridine, without (stain A-IV), although stain A-IV has a greater aziridine/IPBC ratio (1/2 vs. 1/3 and 1/4, respectively).

Example 8 Use of Inventive Nitrogen-Containing Inorganic Carrier Materials in Binder Formulations

The IPBC compositions from Examples 3, 4 and 5 are incorporated in a commercial high-build wood stain “alkyd stain B” (containing alkyd resin, white spirit, iron oxide pigment, dryer, butanone oxime, UV absorber and additives). To equip the coating system with 0.7% IPBC in each case, based on the stain, the compositions of Examples 3, 4 and 5 and also unstabilized IPBC are used in each case (see Table 4):

The high-build stains under investigation, each equipped with 0.7% IPBC (alkyd stain B-I to alkyd stain B-IV), were prepared by mixing the weight fractions of the alkyd stain B as indicated in Table 4 and also the stated IPBC-containing compositions.

For determining the stabilization, an accelerated ageing test is carried out. For this purpose, the equipped paint system is introduced into tightly sealing 200 ml glass bottles, with only a minimum, residual amount of air remaining in the container, and stored at 40° C. The results can be seen from Table 5, whereby only the alkyd stains B-I to B-III, equipped in accordance with the invention, exhibit no significant degradation of the IPBC after 4 weeks of storage at 40° C. For the alkyd stains I and II a good stability of IPBC is found even after 8 weeks of storage at 40° C.

Example 10 Use of the Nitrogen-Containing Inorganic Carrier Materials of Examples 9a to 9f in Binder Formulations

The nitrogen-containing inorganic carrier materials from Examples 9a to 9f are incorporated in a typical, alkyd-based coating system (alkyd stain A) in the presence of a transition metal dryer (Co) and a metal oxide pigment (iron oxide).

The formula for the alkyd stain A used is shown in Table 6.

To determine the stabilization, an accelerated ageing test is performed. For this purpose, the equipped paint system is introduced into tightly sealing 200 ml glass bottles, with only a minimal residual amount of air remaining in the container, and stored at 40° C. The results can be seen in Table 7.
